nAsAL noucnn Specification of Letters Patent. v I Pgttnted Rial, 15 1921.

Application filed June 6, 1919. Serial No. 302,093.

T all whom it may concern:

Be it known that '1, JOHN HENRY HERON,

' a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Nasal Douches, of which f the following is a specification.

T may be used to irrigate both the anterior and posterior nasal passages.

"The features of constructionand the peculiar shape of the device provide a douche which may be readily cleaned, which pref-. erably is formed of glass or' porcelain in one piece and which may be readily and quickly used and which does notrequire the application of the hands or fingers of the user to either the filling or discharge end.

One feature of the invention is to be found in the fact that the one piece construction and the absence of corners and pockets renders it possible to readily sterilize the apparatus, a feature not to be found in the usual constructions where usually a multiple number of parts are provided to afford a restricted discharge passage and nose piece connected to a main reservoir.

One of the principal. features of the invention resides in the fact that the extensions provide passageways which constitute continuations of the bore of the douche and because the discharge end of the douche is as large as is desirable for insertion in the nostril, the fluid matter in the douche may flow quickly into the nose of the user with a washing movement. This feature is a marked contrast to douches now known in which the irrigating medium must flow through a restricted passageway and is clesigned to effect a steady'fiow from a reservoir.

Another object of the invention is to provide a douche which may hold approximately one mouthful of nose wash, which amount may be drawn into the nose by one slight suction movement of the nose and throat. This amount will flow freely with a sudden washing movement back over the posterior portion of the nasal passages and will cleanse the tonsils and other parts, such as adenoids, the single mouthful being drawn down into the mouth without causing a gagging so common in the use of continuous flow douches.

' In addition to the above features the shape of the douche renders it impossible for the douche to stand with its intake and discharge openings upright and thus renders it difiicult for falling dust and germs to'enter either opening. Likewise the endsare not permitted to rest on anysupporting surface. v

The construction of the douche is illustrated in the accompanying drawing in which Figure 1 is a side perspective View "looking slightlydownward on the douche and illustrating the inlet and discharge end covering caps removed from their positions.

Fig. 2 is a view looking downward on the structure shown in Fig. 1 but with the coveringcaps'not shown.

i Fig. 3 is a view illustrating a section taken on the line 83 of Fig. 1 and looking inthe direction of the arrows, the covering cap on the discharge end being shown-in position.

Referring in detail to the drawings, 1 is the main body portion having a central space 2 for the irrigating fluid. The filling extension 3 projects substantially at right angles from the part 1 and is provided with an opening 4 through which the irrigating material is adapted to be inserted.

boreof the filling extension 3 is continued I smoothly into the space@ to provide for the free flow of material and the ready cleansing of the douche. The discharge extension 5 is located at the opposite end of the main body portion 1 and also extends sub.- stantially at right angles thereto, and in substantially the same plane with the extension 3. A discharge opening 6 is illustrated as being shaped so as to conform to the contour of a nostril opening. It will be noted that both the openings 4i and 6 lie in substantially the same plane. The extension 5 has a bore substantially as large as the end of the extension and sufliciently large to permit the rapid discharge of the contentsrof the douche in one snufiing movement by the user. Because of the direction of projection of extensions 3 and 5 the material used will not escape out of either opening while the user holds the douche until i the discharge opening and the bore of the inch beyond a pointitaken at the middle of extension leading thereto will permit the flow of a single dose or mouthful of irrlgat ing material regardless of the closing of the filling end. It will be noted that the sides 1 of the body portion 1 are slightly flattened and that the bottom and ends of the part 1 are curved to prevent the douche from remaining upright. Even when lying on one of the flattened sides the douche may retain a full dose, approximately one mouthful, for the reason that the inlet and discharge extensions are maintained in a horizontal position and material would not flow from the body portion. A metallic inlet cover cap 7 is illustrated in Fig. 1 and is adapted to close the filling end of the douche, and a corresponding discharge outlet cover cap 8 is provided for closing the outlet end and is designed to conform to the contour of the outlet end.

The material of construction of the douche is preferably glass, although the invention lncludes the use of any othermaterial, which may be suitably hygienic.

One satisfactory size of the device has been found to, have a length of three and one-half inches, a diameter through the body portion of one inch, and the inlet and outlet extensions projecting about three-quarters of one the side of the body portion from which the extensions project.

I claim:

1. A nasal douche comprising a main liquids, and two tapered extensions projecting from opposite ends of said body portion substantially at right angles thereto and in substantially the same plane, the outer surface of the side of said body portion opposite the said extension being curved and the opposite adjoining sides being flattened, the ends of the tapered, ex-

body portion having a central space for tension projecting laterally and being thus a spaced from the object on which the douche rests.

2. A nasal douche comprising a main body portion having a central space for liquids, and two extensions projecting from opposite ends of said body portion substantially at right angles theretoand in substantially the same plane, the outer surface of the side of said body portion opposite the said extension being curved and the opposite adjoining sides being flattened whereby the douche normally tends to rest on one oi the fl,atte11ed sides with the extensions projecting laterally and the ends being thus spaced from the object on which the douche rests. V

In testimony whereof I afiix my signature.

JOHN HENRY HERON.
